ROLLING-INILL.

Application lef August 20, 1914.

vtype of rolling mills known as a finishing mill and it has for its objects to facilitate the manipulation of the rolled product, to bring the groups of finishing rolls into separate trains, to render the grouping of the rolls more compact and. particularly, to render the mill capable of a great variety of. finished product. These objects, among others, I accomplish by the construction and arrangement of parts as hereinafter described` the novel features being` pointed out in the annexed claims.

Referring to the. accompanying drawings, Figure 1 represents a plan view of a rolling mill embodying my improvennint` haring means for reversing` the niovement of the rolled product. Fig. 2 represents a plan -sievv of the finishing mill arranged for the, continuous reduction of the rolled product, and Fig. l an end view. of the roll housings in the two trains of rolls.

Sin/lila r reference, characters referto Similar parteA in the different figures.

Referring to Fig. 1, 1 denotes a train of rolls forming what is known as a roughing mill for the initial reduction of a billet as it is received from a heating furnace. From the roughing mill. lfthe rolled prod net is delivered through a guide 2 and the first train 3 of finishing rolls comprising. in the present instance, two stands of rolls 4 and At the aidel of the train 3 is a second train 6 of finishing rolls comprising, in the present instance` two stands of rolls 7 and S. The rolls in the train 3 are. independently driven in the opposite direction from that of the rolls in train G by any `aiitable means, in the present instance by independent motors M, M, which permit the speed of thel rolls iu each train to be independently varied.

'lhe rolled product is delivered through the guide 2 upon a feed table 9 having at the end next the train of finishing rolls skew rolls 10 and at the opposite end the,

specification of Letters Patent.

feed rolls 11. The feed rolls 10 and 11 are driven hy a common shaft 12 to continue the movement of the rolled product until its end is \\'il:hdra\vn from the guide 9. The feed rolls 10 and 11 are then reversed to feed the heated metal to the Stand of rolls It, the skew rolls lll deflecting the advancing end of the rolled metal to`bring it intri alinemeut with the passes in the rolls el. From the rolls l the product is conducted through a guide 18 to a 'feed table 14 having" feed rolls 15 and shew feed rollsv 16, similar to the feed table 9. 'lllie rolls 15 and 1G are dri\ en b v a common shaft 17 to remove the i rolled product from the guide .153, when the feed rolls 15 and 1H are reversed and the rolled product fed to the stand of rolls` 7 from which it is delivered through a guide 1S to the feed table 1S) provided with feed rolls 20 and 21, similar to feed table 9, and driven by :i common shaft-252. By the reversal of the feed rolls 20 and Q1, the rolled metal is conducted to the stand of rolls 5, from which it is delivered through a guide to a feed table 21 provided with feed rolls 25 and 26 driven bj a couimon shaft 27. Bv reversing the feed rolls Z5 and 26,

the rolled product is. conducted to the final stand of rolls S and from them delivered to a guide 2% by which it may be conducted to a cooling bed or reel, as desired.

In Fig. 2 l have shown the same trains of finishing rolls` as shown in Fig. 1, but with the two trains preferably separated farther apart to facilitate the manipulation of the rolled metal which is conducted from the roughing mill 1 through the. guide Q and through the loop 29 to the first stand of rolls l. From the stand of rolls et the metal is conducted through a loop 30 to the sand 7 and from the stand 7 through a loop 31 to the stand 5. From the stand 5 the metal is conducted througl'i a loop 32 to the stand 8 from which it is lelivered to the guide i8.

By placing the rolls` in the train lin stag gered relation to the rolls in the train 3 and driving the rolls in cach train in opposite directions, l aceomplish the reversal in the movement of the rolled vmetal by emiglloying two-high rolls only, as reprfented in Fig. 1n Fig. 1 the reversal is accomplished by reversing the movement' of the feed rolls in each of the, feed tables fl, lili, 15) and 24, while in Fig. the metal conH ducted through suitable grooves, guides or lei iOO channels such as are usually employed in forming loops in rolling inills, and the reverse movement of the metal is :iccomplisned by the rolls themselves, mulling the movement of the rolled prodlnct continuous l"through both trains of rolls. AIf the metal is 'conducted from the roughing mill l on the broken lino 33, Fig. 2, rolls 4 and 7 will be omitted, or the metal may ne conducted on the dot and dash line 3l, omitting the stands and 7, and finishing the product in either ease with two passes. lhile I have shown but two stands of rolls in either train, the number of stands may be varied.

I claim,

1. A rolling mill, comprising two tra-ins of rolls with their axes substantially parallel. with the rolls in one train in Staggcred relation to the rolls in the other train, and means for independently rotating the rolls of one train in the opposite direction to the rolls in the other train.

2. A rolling mill, comprising two trains of rolls, means for independently rotating the rolls in each train in opposite direntions`r the rolls in one train being in staggered relation to the rolls in the other train, and means for conducting the metal alternately from one train t the other.

3. A rolling* mill, comprising a roughing train und tw: trains of finishing rolls, with the rolls of one finishing train in staggered relation to the rolls of the other finishing train, means for independently rotating the rolls in each finishing train from corresponding ends of the trains, and means for conducting the metal from said roughing train to one of said trains of finishing rolls.

4. A rolling mill, comprising two trains of rolls with their axes substantially parallel, with the rolls 0f one train in staggered relation to the rolls of the other train` and means for independently rotating the rolls of one train in opposite direction to the rolls of the other trein and at different angular velocities.

5. A rolling mill, comprising :i roughing train and two trains of finishing rolls. means for rotating the rolls of each train of finishing rolls in op osite directions, and means for reversing-tie movement ot the metal at erich of seid trains of finishing rolls.

6. A rolling'mill, comprising two trains of finishing rolls, a feed table for each pair of rolls in Said trains. said feed tables having positively dri\ en conveyor rolls bv which the movement of the metal product can be reversed7 with the con'veyer rolls of' said feed tables next the rolls of said trains having their axes diagonal to the movement of the metal product.

Dated this fourteenth day of August i914.
